BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The invention can be more fully understood by reading the
subsequent detailed description and examples with references made to the
accompanying drawings, wherein:

[0013] The following description is of the best-contemplated mode of
carrying out the invention. This description is made for the purpose of
illustrating the general principles of the invention and should not be
taken in a limiting sense. The scope of the invention is best determined
by reference to the appended claims.

[0014] Referring to FIG. 1, a full steam-driven internal-combustion engine
using an extended gas supply system comprises a mechanical power system,
a combustion system and a gas supply system.

1. Combustion System

[0015] In the combustion system, a high-pressure gas produced by
deflagrating a fuel air mixture is ejected from a high-pressure nozzle to
form a high speed power source. The combustion system includes two main
cylinders and an auxiliary device. The two main cylinders, a left main
cylinder 3a and a right main cylinder 3b, are interactively operated.
That is, when the left main cylinder 3a does work, i.e., when
high-pressure hot gas clusters produced by deflagrating the fuel air
mixture in the left main cylinder 3a are ejected from the pressure nozzle
at a high speed, a gas sucking process is completed by the right main
cylinder 3b.

[0016] Each of the left/right main cylinders 3a/3b includes an assembly of
a cylinder housing and a piston. In the left main cylinder 3a, an intake
valves 19, an exhaust valve 20, an electric sparkling plug 18, and a left
high-pressure gas valve 11a communicated with a high-pressure gas pipe 17
are disposed on a bottom portion of the cylinder housing. In the right
main cylinder 3b, an intake valves 19, an exhaust valve 20, an electric
sparkling plug 18, and a right high-pressure gas valve 11b communicated
with a high-pressure gas pipe 17 are disposed on a bottom portion of the
cylinder housing. Two high-pressure nozzles are respectively disposed in
the vicinity of side surfaces of top portions of the outer housings of
the left/right main cylinders 3a/3b. The left/right main cylinders 3a/3b
have the same structure.

[0017] The operation of the left/right main cylinders 3a/3b comprises the
following steps.

[0018] i) The piston is moved from the bottom portion to the top end of
the cylinder, and the fuel air mixture is sucked into the cylinder via
the intake valves 19.

[0019] ii) The piston of the main cylinder is stopped to seal the
high-pressure nozzle when the piston is moved to the position of the
high-pressure nozzle thereof.

[0020] iii) The fuel air mixture located in the main cylinder is ignited
by the electric sparkling plug 18.

[0021] iv) The piston is upwardly pushed by the high-pressure gas produced
by deflagrating the fuel air mixture; meanwhile, the high-pressure gas is
accelerately ejected from the high-pressure nozzle.

[0022] v) When the high-pressure gas mostly is ejected from the
high-pressure nozzle, the main cylinder is filled with the waste gas.
Then, the piston begins to downwardly move from the top end of the
cylinder to expel the waste gas therein through the exhaust valve 20. A
working process of the cylinder is completed until the piston is moved to
the bottom portion of the cylinder to expel the waste gas in the
cylinder.

[0023] The auxiliary device of the left/right main cylinders 3a/3b
comprises left/right air-compressive flexible devices 5a/5b, a left
auxiliary cylinder 4a, a right auxiliary cylinder 4b, left/right levers
"A" 6a/6b, left/right levers "B" 7a/7b, a left high-pressure gas pipe
12a, a right high-pressure gas pipe 12b, left/right linkages "A" 8a/8b,
left/right linkages "B" 9a/9b, and left/right cam spindles 10a/10b. With
the left high-pressure gas pipe 12a, the bottom portion of the left main
cylinder 3a is connected to the bottom portion of the right auxiliary
cylinder 4b which is belong to the right main cylinder 3b. With the right
high-pressure gas pipe 12b, the bottom portion of the right main cylinder
3b is connected to the bottom portion of the left auxiliary cylinder 4a
which is belong to the left main cylinder 3a. Two one-way flexible valves
are respectively disposed in the left/right high-pressure gas pipes
12a/12b.

[0024] The left/right air-compressive flexible devices 5a/5b of the
invention have the similar functions as that of the huge spring of the
conventional full steam-driven internal-combustion engine. In the working
principle of the left/right air-compressive flexible devices 5a/5b, the
elasticity is produced by compressing the air. The left/right
air-compressive flexible devices 5a/5b, arranged substantially being
parallel to the left/right main cylinders 3a/3b and the left/right
auxiliary cylinders 4a/4b, are respectively disposed in between the left
main cylinder 3a and the left auxiliary cylinder 4a and in between the
right main cylinder 3b and the right auxiliary cylinder 4b. Herewith, it
is understood that the air-compressive flexible device has a small, a
high elasticity produced, and a reliable and firm structure.

[0025] The left/right air-compressive flexible devices 5a/5b have the same
structure, and each of which comprises an outer housing and a piston,
wherein the piston includes a top end connected to the left/right levers
"A" 6a/6b. The left/right auxiliary cylinders 4a/4b have the same
structure, and each of which comprises an outer housing and a piston. The
housings of the left/right auxiliary cylinders 4a/4b have bottom portions
respectively disposed with an exhaust valve 21, and the pistons of the
left/right auxiliary cylinders 4a/4b have top portions respectively
connected to the left/right levers "B" 7a/7b. The pistons of the
left/right main cylinders 3a/3b are fixedly connected to the pistons of
the left/right air-compressive flexible devices 5a/5b via the left/right
levers "A" 6a/6b, respectively. The top portions of the pistons of the
left/right auxiliary cylinders 4a/4b are fixedly connected to the
left/right levers "B" 7a/7b, respectively.

[0026] The left/right levers "A" 6a/6b and the left/right levers "B" 7a/7b
are disconnected to each other, respectively, logically designed to
replace a coordination card in the conventional combustion system. The
left/right linkages "A" 8a/8b have first ends, which are hinged to the
top ends of the left/right levers "B" 7a/7b disposed on the pistons of
the left/right auxiliary cylinders 4a/4b via two metallic pins,
respectively, wherein an angle formed between the linkage "A" and the
lever "B" can be changed. The left/right linkages "A" 8a/8b have second
ends, which are hinged to the ends of the linkages "B" 9a/9b via two
metallic pins, respectively, wherein an angle formed between the linkage
"A" and the linkage "B" can be changed.

[0027] The linkages "B" 9a/9b have ends fixedly connected to the ends of
the left/right cam spindles 10a/10b, respectively. Each of the left/right
cam spindles 10a/10b includes four cams, corresponding to the intake
valves 19 and the exhaust valves 20 of the left/right main cylinders
3a/3b of the combustion system, the left/right high-pressure gas valves
11a/11b of the gas supply system, and the exhaust valves 21 of the
left/right auxiliary cylinders 4a/4b of the combustion system,
respectively. The left/right cam spindles 10a/10b have ends fixedly
connected to the linkages "B", respectively. When the left/right cam
spindles 10a/10b are rotated, the cams of the left/right cam spindles
10a/10b, adequately and sequentially, respectively drive the intake
valves 19 and the exhaust valves 20 of the left/right main cylinders
3a/3b of the combustion system, the left/right high-pressure gas valves
11a/11b of the gas supply system, and the exhaust valves 21 of the
left/right auxiliary cylinders 4a/4b of the combustion system, for
performing opening and closing processes. The other parts of the
left/right cam spindles 10a/10b are relatively fixedly positioned by
steel frames and bearings.

[0028] The working principle of the auxiliary system is described as
follows.

[0029] (1). When the fuel air mixture located inside the left main
cylinder 3a is deflagrated, the piston of the left main cylinder 3a leads
the piston of the left air-compressive flexible device 5a to lift or
upwardly move via the left lever "A" 6a, so that the left lever "A" 6a is
disconnected from the left lever "B" 7a, i.e., the contact relationship
between the left lever "A" 6a and the left lever "B" 7a is terminated.

[0030] (2). When the high-pressure gas located inside the left main
cylinder 3a is partially transmitted to the right auxiliary cylinder 4b
via the left high-pressure gas pipe 12a, the piston of the right
auxiliary cylinder 4b is upwardly moved. With the one-way flexible valves
disposed in the left/right high-pressure gas pipes 12a/12b, it is noted
that the gas flows reaching predetermined pressure are unidirectional
flows traveling from the left/right main cylinders 3a/3b toward the
right/left auxiliary cylinders 4b/4a, respectively.

[0031] (3). When the piston of the right auxiliary cylinder 4b leads the
piston of the right main cylinder 3b and the piston of the right
air-compressive flexible device 5b to lift or upwardly move via the right
lever "B" 7b and the right lever "A" 6b, the right main cylinder 3b sucks
the fuel air mixture therein.

[0032] (4). With the right linkage "A" 8b and the right linkage "B" 9b to
be leaded by the piston of the right auxiliary cylinder 4b and the right
lever "B" 7b, the right cam spindle 10b is rotated to drive the cams to
simultaneously open the intake valves 19 and the right high pressure air
valve 11b of the right main cylinder 3b.

[0033] (5). When the high-pressure gas located inside the left main
cylinder 3a is almost ejected, the piston of the left air-compressive
flexible device 5a simultaneously pushes the piston of the left main
cylinder 3a and the piston of the left auxiliary cylinder 4a via the left
lever "A" 6a and the left lever "B" 7a to downwardly move.

[0034] (6). The left air-compressive flexible device 5a drives the left
cam spindle 10a to rotate via the left lever "A" 6a, the left lever "B"
7a, the left linkage "A" 8a and the left linkage "B" 9a, so that the cams
of the left cam spindle 10a drive the exhaust valve 20 of the left main
cylinder 3a and the exhaust valve 21 of the left auxiliary cylinder 4a
for opening, respectively.

[0035] (7). The waste gases located in the piston of the left main
cylinder 3a and the piston of the left auxiliary cylinder 4a are expelled
when the piston of the left main cylinder 3a and the piston of the left
auxiliary cylinder 4a are moved to the bottom portions thereof. The right
main cylinder 3b is filled with the fuel air mixture when the piston of
right main cylinder 3b is moved to the position of the right
high-pressure nozzle thereof

[0036] (8). When the fuel air mixture located in the right main cylinder
3b is deflagrated, the piston of the right main cylinder 3b leads the
piston of the right air-compressive flexible device 5b to upwardly move
via the right lever "A" 6b, so that the right lever "A" 6b is
disconnected from the right lever "B" 7b, i.e., the contact relationship
between the right lever "A" 6b and the right lever "B" 7b is terminated.

[0037] (9). When the high-pressure gas located inside the right main
cylinder 3b is partially transmitted to the left auxiliary cylinder 4a
via the right high-pressure gas pipe 12b, the piston of the right
high-pressure gas pipe 12b is upwardly moved.

[0038] (10). When the piston of the left auxiliary cylinder 4a leads the
piston of the left main cylinder 3a and the piston of the left
air-compressive flexible device 5a to upwardly move via the left lever
"A" 6a and the left lever "B" 7a, the left main cylinder 3a sucks the
fuel air mixture therein.

[0039] (11). With the left linkage "A" 8a and the left linkage "B" 9a to
be leaded by the piston of the left auxiliary cylinder 4a and the left
lever "B" 7a, the left cam spindle 10a is rotated to drive the cams
thereof to simultaneously open the intake valves 19 of the left main
cylinder 3a and the left high-pressure gas valve 11a.

[0040] (12). When the high-pressure gas mostly is ejected from the right
main cylinder 3b, the piston of the right air-compressive flexible device
5b simultaneously pushes the piston of the right main cylinder 3b and the
piston of the right auxiliary cylinder 4b to downwardly move via the
right lever "A" 6b and the right lever "B" 7b.

[0041] (13). The piston of the right air-compressive flexible device 5b
drives the right cam spindle 10b to rotate via the right lever "A" 6b,
the right lever "B" 7b, the right linkage "A" 8b and the right linkage
"B" 9b, so that the cams of the right cam spindle 10b drive the exhaust
valve 20 of the right main cylinder 3b and the exhaust valve 21 of the
right auxiliary cylinder 4b for opening, respectively.

[0042] (14). The waste gases located in the left main cylinder 3a and the
left auxiliary cylinder 4a are respectively expelled when the piston of
the left main cylinder 3a and the piston of the left auxiliary cylinder
4a are moved to the bottom portions thereof. The right main cylinder 3b
is filled with the fuel air mixture when the piston of right main
cylinder 3b is moved to the position of the right high-pressure nozzle
thereof.

[0043] (15). When the piston of the left main cylinder 3a and the piston
of the right main cylinder 3b continuously and alternatively do works,
the auxiliary system of the left main cylinder 3a and the auxiliary
system of the right main cylinder 3b repeat the above-described movements
and processes.

[0044] The auxiliary systems are utilized to assist the left/right main
cylinders 3a/3b in actuating to each other when the left/right main
cylinders 3a/3b do work, respectively. The left main cylinder 3a, the
left auxiliary cylinder 4a, the left air-compressive flexible device 5a,
the right main cylinder 3b, the right auxiliary cylinder 4b and the right
air-compressive flexible devices 5b are fixed by steel frames.

2. Mechanical Power System

[0045] With the mechanical power system, the high-pressure and high-speed
hot gas flows, produced by the left/right main cylinders 3a/3b and
ejected from the high-pressure nozzles, are converted into mechanical
rotation. The mechanical power system includes a large-diameter turbine
wheel 1 and a turbine shaft 2 used for the turbine wheel 1 and
longitudinally extended to the bottom of the internal-combustion engine.
The turbine wheel 1 is rotatably fixed by a steel frame and a bearing.

[0046] The working principle of the turbine wheel 1 is that the turbine
wheel 1 is rotated by propelling turbine blades when the high-speed ad
high-pressure gas flow is acted on the turbine blades. The turbine shaft
2 driven by the turbine wheel 1 continuously outputs a mechanical work to
drive an air compressor 15 of the gas supply system.

3. Gas Supply System

[0047] With the gas supply system, an oxygen gas is sufficiently supplied
to the left/right main cylinders 3a/3b for combustion. The gas supply
system comprises the air compressor 15, a transmission shaft 14 connected
to the air compressor 15 and turbine shaft 2 of the mechanical power
system, a high-pressure gas pipe 17, and the left/right high-pressure gas
valves 11a/11b.

[0048] The working principles of the components of the gas supply system
are described as follows. The air compressor 15 utilizes the continuous
rotation of the transmission shaft 14 as a power for converting the
high-pressure air. The transmission shaft 14 is utilized to transmit the
energy from the turbine shaft 2 to drive the air compressor 15. The
high-pressure gas bottle 16 is utilized to store and sufficiently supply
a high-pressure air to the left/right main cylinders 3a/3b for
combustion. When the left/right cam spindles 10a/10b are rotated, the
cams of the left/right cam spindles 10a/10b adequately push the
left/right high-pressure gas valves 11a/11b for opening or closing,
adequately enabling the high-pressure gas to enter the left/right main
cylinders 3a/3b via the left/right high-pressure gas valves 11a/11b and
the intake valves 19.

[0049] The high-pressure gas pipe 17 is a high-pressure gas passage
utilized to connect the air compressor 15, the high-pressure gas bottle
16, the left/right high-pressure gas valves 11a/11b, and the left/right
main cylinders 3a/3b. The transmission shaft 14 is rotatably fixed by a
steel frame and a bearing. The air compressor 15, the high-pressure gas
bottle 16, and the left/right high-pressure gas valves 11a/11b are fixed
by steel frames.
